Doppler shift Say a mobile phone moving at velocity v km/hr in the x direction and the radio wave impinging on the receiver at an angle βk.

If the ray is directed opposite to the mobile\u2019s motion (\u03b2=0), then fk=v/\u03bb. The frequency of the signal has increased by the Doppler spread, fk.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
